Brit.

/ˌpaljᵿˈdʌɪnə/,

/ˌpaljᵿˈdiːnə/, U.S.

/ˌpæljəˈdaɪnə/,

/ˌpæljəˈdinə/

Inflections: Plural Paludinas, Paludinæ.

Origin: A borrowing from Latin. Etymon: Latin Paludina.

Etymology: < scientific Latin Paludina (attributed to Lamarck by A. de Férussac 1812, in Ann. Mus. d'Hist. Nat. Paris 19 253) < classical Latin palūd- , palūs palus n.¹ + -īna -ine suffix¹. Compare French paludines, plural (1812). N.E.D. (1904) treats this as non-naturalized and gives the pronunciation as (pælⁱudəi·nă) /pæl(j)uːˈdaɪnə/.

Zoology. A genus of freshwater snails (pond snails), now usually called Viviparus; (also paludina) a snail of this genus.
